Secondly the way Google determines the demographic is via the site content.
Or to put it another way; site owners don't have a "right" to Adsense. Google is clearly allowed to choose those sites it considers "to be good advertising sites".
Therefore if you have a site that doesn't offer good advertising opportunities, then don't be surprised if people don't want to advertise on it.
To be clear, I'm not saying all sites should be ad friendly. I'm saying that advertising alone cannot prop up every site, useful or not.
If Google had competition in the ads space, this would be less of an issue, as the author could pick an advertiser that works for their website, rather than contorting their website for google
Or to put it another way, what product should this be advertising on this site? Because there are a lot of companies in the world, so of you can identify just one of them, they'll likely pay enough for exclusivity.
Though people are doing that with SEO anyway so it is a weird game.
I think maybe all ads would need to be the same value to fix a lot of the nonsense. But I don't know if that could ever work, especially with how seasonal ad revenue is.
Then, ban pages that change their audience too often.
But, as a thought exercise. Let's say you were selling ads directly to the business paying. Which businesses do you suppose might be interested on a congressional apportionment calculator?
Political ads? Campaign ads?
Newspapers advertising that they've got the fastest election news?
People looking for an apportionment calculator are likely interested in a past or future election and interested in political topics. That's a lot of potential ads you could show.
So if there us the value you suggest, it should be an easy sell. Probably less work than he went to to tweak the site.
Then again, are people investigating vote targets undecided voters? And good luck getting media to advertise....
But even on YouTube it's back nowadays, most YouTubers get their money from sponsorships which work just the same as old-school pre-internet ad placement.
But seriously, there are plenty of ads that are based on geo located IP. Then of course there’s the cookie (and cookie replacement) ads.
Complaining about site content is pretty bogus.
And indeed, that cuts the site operator out of the loop, and forces them (if they want to make money from these ad algorithms) to design a site that will attract users with easily-intuited advertising needs. And the linked article doesn't have that.
[1] And still do in parallel niche markets like porn.
As soon as it can be gamed, it will be gamed. It's just the scammy nature of it all. Now that it's "AI" generated content, it will get to enshitified almost immediately on any system that is created
Why are words so important?
